I highly, highly recommend this book to anyone who either is taking a course in cryptography in school or wants to learn about it. It is a very well written book which clarifies a lot of basic concepts. I bought it as it was recommended by my professor in school and managed to get an A in the course. It is a good book and I think it helped me come back after a lecture and find all the matter that I needed. Good reference material.Was this review helpful? Yes NoThank you for your feedback.

digital cash and quantum cryptography
Trappe and Washington give us a very up to date education in cryptography, circa 2005. The discourse is for a sophisticated maths student who, however, need never have encountered cryptography before. The level of mathematical treatment is good and rigourous. With theorems stated and proved at a level that should satisfy even a picky mathematician. The recent nature of the book is reflected in several places. Notably where it explains the Advanced Encryption Standard, or Rijndael. This is significant because it is endorsed by the US National Institute of Standards and Technology as the replacement for DES, in such contexts as electronic commerce. (DES is also covered by the book.) Interestingly, the authors offer a short chapter on digital cash. A fascinating look at a possible future direction of a (physically) cashless society. Other texts on cryptography rarely cover the topic, so it's good to see it here. Yes, the first implementations of digital cash largely died in the dot com crash. But the idea lives on, and may yet take fruit. It has solid intellectual foundations, as shown by the book. Then there is an even more speculative chapter on quantum cryptography. Radically different from the symmetric and public key cryptosystems described in the rest of the book. Who knows how quantum cryptography will turn out? Some very hard physical problems need to be solved.Was this review helpful? Yes NoThank you for your feedback. Report this reviewThank you, this review has been flagged.
